摘　　要：添加外源酶制剂能够显著提高反刍动物对碳水化合物的吸收和对蛋白质的利用率,但目前以奶牛、肉牛方面的研究为主,在羊生产中缺乏相应的研究。文章就外源酶制剂国内外研究概况、对反刍动物的作用机理以及对羊生产性能、瘤胃微生物发酵参数和微生物种群的影响进行综述,以期为外源酶制剂在羊生产中的广泛应用提供参考。Addition of exogenous enzymes can significantly improve the absorption of carbohydrate and the utilization rate of protein in ruminants.However,the studies are mainly focused on cows and beef cattle,and there is a lack of more extensive research in sheep production.In the paper,the research status of exogenous enzymes,the mechanism of exogenous enzymes on ruminants,and its effects on sheep production performance,rumen microorganisms fermentation and microbial population were reviewed,to provide a reference for wider application of exogenous enzymes in sheep production.
